Understanding the AQI
The purpose of the AQI is to help you understand what local air quality means to your health. To make it easier to understand, the AQI is divided into six categories:

Category	AQI	Color Code	Health Statements
Good	1 - 50	Green	No health impacts are expected when air quality is in this range.
Moderate	51-100	Yellow	Unusually sensitive people should consider limiting prolonged outdoor exertion.
Unhealthy for Sensitive Groups	101-150	Orange	Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
Unhealthy	151 - 200	Red	Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion.
Very Unhealthy	201-300	Purple	Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
Hazardous	301-500	Maroon	AQI values over 300 trigger health warnings of emergency conditions. The entire population is more likely to be affected.
